The conical filter also known as temporary filters, as the name suggests its shape as the vertebral body, belong to the pipeline coarse filter series. Its simple form, the device is working properly and operation to remove impurities in the medium inside the tubes, stable process, to ensure the safety of equipment production. The principle of fluid into the cartridge, the impurities are blocked, the cleaning fluid outflow exports tapered cartridge needs cleaning, simply remove the load can after cleaning, cone filter characteristics: mainly used in the car before the pipeline, installed between two flanges in the pipeline, the device is simple, reliable, convenient and widely applicable. The cone filter is divided into: the sharp end of the conical filter, flat-bottomed cone filter Scope: 1. Petrochemical production process weak corrosive substances. 2 chemical production corrosive materials. 3. Refrigeration in the low-temperature materials. Light food, pharmaceutical production materials hygiene requirements.
